Ditching his red-carpet tuxedo shorts for his trademark hat of ridiculousness, Pharrell got things started with Despicable Me 2‘s “Happy.” There were big lights, there were tiny dancers and there was so much shimmying from Meryl Streep.

Next up was Karen O with a far more low-key performance of “The Moon Song” from Her. Not only did Ms. O sound great, but she also went barefoot, which is a bold move for anyone at The Oscars.

Bono and his colorful glasses (and those others guys from U2) then took the stage for an acoustic performance of Mandela‘s “Ordinary Lives.” The song was met with a standing ovation, led by Jared Leto.

Not related to any of this year’s nominees, but still worthy of a spot in this post, was Pink’s cover of The Wizard of Oz‘s “Somewhere Over the Rainbow.” We weren’t surprised that Pink sounded great, but we were surprised she remained on the ground the entire time.

Another performance unrelated to any of this year’s films was Bette Midler’s “Wind Beneath My Wings,” which she sang following the “In Memoriam” portion of the Oscars.

Lastly, and perhaps definitely most highly anticipated, Frozen star Idina Menzel belted out an unforgettable rendition of “Let It Go.” (And yes, her name is Idina Menzel, regardless of however John Travolta chose to introduce her. Seriously, what did he say?)
